Grain shipping costs on the Mississippi River have surged to an almost eight-year high as importers, including China, turn to U.S. soybeans and corn. Dry weather in Brazil and Russia's invasion of Ukraine, which has halted Black Sea corn shipments, drive the demand shift.
Barge rates at St. Louis reached $34.75 per short ton, the highest since 2014.
Higher barge freight raises the delivered cost of U.S. grain and meal to Gulf export terminals and inland feed buyers, supporting domestic corn and soybean basis and feed costs. Elevated water levels also cut barge loads by about 15%, tightening capacity further.
